Way #1
Who is Number One?
You are Number Six.
Way #2
Who is Number one?
You are, Number Six.
There are two ways to read the opening dialog.
Way #1
Who is Number One?
You are Number Six.
Way #2
Who is Number one?
You are, Number Six.
+++++
Considering his interrogator/host is Number Two, not Number One as one might expect, Way #2 has considerable merit.
Thanks for your insight.
